Patented Sept. 17, 1929 UNITED STATES PATENT OFFICE SPIN NING-FRAME-LUBRICATING DEVICE Application filed February 15, 1928.

This invention relates to the lubrication of spindles and bobbin tubes such as are used in cap spinning frames.

In such frames there is a row of spindles which are fixed to the frame and which pass up through holes in a lifter plate which moves up and down to build the yarn on the bobbins.

At the top of each spindle is fixed a cap and each bobbin is carried by a tube at the bottom of which is a pulley or whirl which rests on a bearing or directly on the lifter plate. Each whirl and tube, carrying along the bobbin, revolves on the spindle and at the same time the bottom of the tube or whirl rests either on the lifter plate or on a bearing carried thereby.

The space between the tube and spindle must be lubricated and it is desirable that the bottom end of the tube or whirl either should be lubricated or should carry with it some sort of a bearing which is lubricated.

I am aware that various types of so-called washers or bearings have been used between the lifter plate and the bottom of the tube or whirl, but my present invention involves an assembly of parts by which the wear is great ly reduced and the frequency of oiling is much less, while the lubrication is better.

In my device it is necessary to oil only once a week instead of once a day and there is no danger of the oil flying out or of the parts stopping up.

Whatever wear there is comes on comparatively inexpensive and easily replaceable parts. The oil absorber is so positioned that it will not curl nor rumple up.

In the drawings, Fig. 1 is a vertical sectional view of a cap spinning spindle, lifter plate, and bobbin tube with whirl, and oiling device all in place.

Fig. 2 is a plan view of the wearing washer.

Fig. 3 is a plan view of the hard fiber oil distributor.

Fig. 4 is a plan view of the absorbent washer.

Fig. 5 is a vertical section of my oil distributor on line 55 of Fig. 3.

Fig. 6 is a view similar to Fig. 5, of a modifi cation in which the wearing washer and oil distributor are integral.

Serial No. 254,527.

In the drawings B indicates a spindle of a cap spinning frame supported at 11 in the usual manner while 12 is the cap carried by the upper end of spindle B. A is a lifter plate which is shown as fiat on the top. H is the tube which carries the bobbin 14 and has formed integrally with it or rigidly keyed thereon, the whirl or pulley 15 which is caused to revolve by means of the usual band or belt 16 as shown.

C is a washer preferably of felt or other absorbent material, preferably of disc form and having a central opening 20 which allows it to be passed over the spindle B and to rest on the lifter plate A.

F is an oil distributor preferably made of hard fiber having a central opening 30 through which spindle B passes with a smooth running fit. From this central opening 30 extends radial channels 31, 31, 31, preferably slightly rising to an annular channel 32 in the top of container F. Extending from either the radial channel or from the annular channel down through the oil container are the oil holes 33, 33, 33.

G is an annular, preferably hard fiber wearing washer having a central opening 40 through which is passed the spindle B with a smooth running fit. This wearing washer G is of a size to rest on top of the fiat part of distributor F extending partly over the radial channels and is of such size that the bottom end 10 of whirl l5 rests comfortably upon it and revolves thereon.

WVith this construction, the wearing washer G crawls on oil distributor F while the bottom of the tube H or the whirl 15 revolves upon it, the space between the two parts receiving a sufficientamount of oil from the spindle which is covered with a film of oil at all times. By my construction, the part F helps to keep the oil moving from top to bottom and from outside to inside while washer C serves as an elastic reservoir which gives to and takes oil from the channels of F.

As the lifter plate A rises, there is a tendency to squeeze absorbent washer C and to press the parts together while when the lifter plate lowers, there is the opposite tendency. This, together with capillary attraction keeps the spindle lubricated and keeps the space be tween the wearing Washer G and the bottom of tube H lubricated. As the wear comes mostly on Wearing washer G which is simple and inexpensive, it can be renewed without renewing the rest of the parts.

The distributor F will last indefinitely as itis protected at top and bottom and While it may crawl to some extent, it does not revolve. The washers C and G are simple and inexpensive and can be easily replaced.

As shown in Fig. 6, I may combine the distributing washer and the wearing washer in one integral member K having a boss 54, central spindle opening 50, radial channels 51, annular channel 52 and oil passage 53.

I claim:

1. The combination with a litter plate; and a fixed spindle which passes therethrough; of an absorbent washer passed over the spindle and resting on the lifter plate; a hard fiber oil distributor having a central opening through which the spindle passes, radial channels extending from said opening to an annular channel and oil holes extending from said channel through the distributor; an annular hard fiber Wearing Washer passed over the spindle and resting on the oil distributor; and a tube revoluble on the spindle and carried by a whirl which rests on said wearing Washer.

2. A hard fiber oil distributor having a central opening through which the spindle passes, radial channels extending from said opening to an annular channel and oil holes extending from said annular channel through the distributor.
